Abstract

Attenuate phase shift masks have been developed for practical use because there are less limitations on the design, and mask defect repairs are easier. However, phase shift mask manufacturing technology improvement is needed not only for control of phase shift or transmission, but also higher accuracy and more precise patterns such as KrF application or for 4X reticle applications. This report shows the manufacturing method of the MoSiON attenuate phase shift mask with Cr border and its quality encourages its evaluation as a promising technique for finer patterns.
